I have been trying to decide what to use as I have been struggling with the length of my keyboard cable. I nearly got a gamepad but have always been wary that it will do everything I want. I also quite like the flexibility of a keyboard. I know most of you use Mach 3 but I use LinuxCNC and that is very keyboard centric arrow keys x and y PGup PGdn Z axis the ,. keys are jog speed Shift + axis keys is rapid move, R is run P is Pause S is resume.

Anyway I can say that is was a good buy, it has a rechargeable battery and a power saving mode so I have only charged it once so far. The keyboard is LED backlit which helps more than I expected. It is no good for typing an essay but great for keyboard commands. It seems to have a practical range of about 6 metres which is plenty for my set up.
